Abstract: The classical Stampacchia lemma has been widely used in the regularity theory of elliptic partial differential equations and systems as well as variational problems. This paper summarizes the Stampacchia lemma and their generalizations, and give an application to the regularity theory of degenerate elliptic partial differential equations.

Key words: Stampacchia lemma, generalization, elliptic partial differential equation, variational problems, regularity
